Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed January 29, 1918. Serial liTo. 214,301.

T 0 all whom it may concern 4 Be it known that I, ANTHONY VASSELLI, a

citizen of the United States, and a resident of the city of Newark, county of Essex, and

"State of New Jersey, have invented a certain By the use of my invention, the motor will always be at rest except when a record is being played, and it will be unnecessary for the operator to release a brake with one hand preparatory to bringing the stylus into position to engage the record groove. No manually operated brake is employed, but an invisible brake mechanism in no manner operating upon or in contact with the turn-table, automatically starting the motor mechanism through which the turn-table simultaneously is started.

One of the objects of my invention is to provide a release mechanism capable of automatically starting the rotation of the turntable, and to provide a brake mechanism operating automatically at a predetermined time, controlled primarily by the length of the record groove or at the point where the reproduction ceases.

Another object of my invention is to provide means to locate the point in the record groove at which the reproduction ceases, and to provide means on the record to indicate such fact for further reference or use.

Another object of my invention is to produce a device whereby the machine may be automatically started and stopped without conscious action of the operator by which the motor will be inoperative except when a record is being played, wherein all of the operating parts are below the turn-table, wherein records of difi'erent lengths may be played, and wherein the stop may be adjusted to suit disks having different lengths of record groove.

A further object of the invention is the provision of means for automatic release and brake mechanism, of the character described, simple in construction, thoroughly reliable and efiicient in its purpose, inexpensive to manufacture, and so designed and constructed that it may be attached to disk talking machines now in general use.

With these and otherobjects in view to be more fully set forth hereinafter, the invention consists in the novel construction, combination of elements, and arrangement of parts which will be exemplified in the construction hereinafter described in the specification and illustrated in the accompanying drawings considered together or separately.

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which for the purpose of illustrating the invention, is shown in the accompanying drawings.

The invention will be first described in connection with the accompanying drawings illustrating one embodiment of my invention, Y wherein similar reference characters are used to designate corresponding parts throughout the several views, and then more specifically defined and indicated in the appended claims.

In the drawings,

Figure 1 is a plan view of a talking machine embodying my invention, with the sound-boX in'position to start playing.

Fig. 2 is a side elevation, partly in section of the same, with the sound-box in position near the end of the record.

Fig. 3 is an end elevation of the same.

Fig. 4 is an enlarged detail plan of a portion of the operating parts of the mechanism.

Fig. 5 is a section on the line 5-5 of Fig. 4.

Fig. 6 is a section on the line 6-6 of Fig. 4; and

Fig. 7 is a section on the line 7-7 of Fig. 4.

In carrying out my invention in the embodiment illustrated, I provide a talking machine having the usual casing or cabinet provided with a motor board 2, a tone-arm 3, a sound-boxer reproducer 4 attached 6O lever 24 located above and at approximately thereto, the latter carrying astylus 5, a turntable 6 carrying a record disk 7 supported above the motor board.

To the under side of the board 2 is secured, in any well known manner, a motor 8, having a driving shaft or turn-table spindle 8 projecting through an opening in the motor, the said spindle board supporting and rotating the turn-table, carrying the record disk 7. The motor is provided with the usual centrifugal governor 9 to the shaft of which is secured a governor disk 10, for purposes hereinafter explained. Carried by the frame of the motor is a brake shoe 11 so adjusted and positioned that the governor disk 10. will engage such brake shoe mechanism when the speed of the motor has reached a definite limit.

Carried in bearings 12 in the motor frame, is a vertical auxiliary spindle 13 projecting through an opening in the motor board 2, the said auxiliary spindle being provided with a button or head 14, for the purposes hereinafter explained. The lower end of the auxiliary spindle 13 has affixed thereto a brake shoe 15 and a coil spring 16 between said brake shoe 15 and the bearings 12, sald springs tending to normally hold the brake shoe 15 in engagement with the periphery of the governor disk 10.

A cam'17 engages the under side of the button or head 14, and said cam is provided with slot 18 having parallel walls; between said walls and passing through said slot projects the auxiliary spindle 13, whereby the cam may move relatively to the said spindle and be guided thereby. The cam 17 is adjustably' mounted on the end of a slide 19, by means of a screw 20 carried by the slide, and a slot in an extension of the cam, in order that the cam may be adjusted toward and away from the auxiliary spindle 13. The

sides of the extension of the cam are formed into downwardly projecting flangesto guide the cam in its movements relatively to the slide. Theslide 19 extends across the motor board 2 in close proximity to the center of the turn-table, in the direction of the tonearm, and rests upon and is guided by a base plate 21 through the upwardly extending parallel projections 21. Said base plate being secured to the top of the motor board. The slide 19 has'removably and slidably atfixed to it at and nearest the turn-table spindle 8 the cam 17, and at the opposite end the said slide is provided with an anti-friction roller 22. Between the cam and the anti-friction roller the slide is provided at one side with a shallow ratchet tooth 23.

Pivoted to the base plate 21, at 23 is a right; angles tothe slide 19. One end of the lever is curved on an arc, the center of which is the pivot. of the tone-arm 3, and the said lever is provided with a curved slot 25 having the same radius. Mounted upon the curved extremity of the lever 24 is an auxiliary slide 26 provided with a down-turned flange 27 engaging one side of the lever and preventing rotation of said slide. The auxiliary slide is provided, on the side nearest the tone-arm, with a downwardly extending projection 28 for a purpose to be hereinafter specified. The said slide carries a bolt 29 projecting through the slot 25, said bolt having a washer 3O riveted to its lower end, Between the lever 24 and the washer 30 is a spring washer 31.

The lever 24 is provided at the end opposite the curved slot 25, with a projection 32 at right angles to the lever, said projection forming a pawl for engagement with the shallow ratchet tooth 23. A spring 33 attached to the projection 32, at 32*, and the slide 19 at 33 tends to normally hold the latter in such position that the pawl will be disengaged from the tooth. The engagement of the pawl with the untoothed portion of the slide will limit the movement of the lever 24 in the direction toward the tonearm, and a stop 34 on the base plate will limit the movement of the lever in the op- ;osite direction.

Pivoted on the bolt 29 is a link 35, the opposite end of which is pivoted at 35 to one arm of a bell crank lever 36 pivoted at 36 on the base plate. The other arm of the bell crank lever has mounted thereon a screw bolt 37 projecting through a slot 38 near one end of a pitman 39. The screw bolt 37 is provided with a. nut 40 having an extension 41 projecting into the slot 38. The opposite end of the pitman 39-enters a casing 42 situated in Such a position that it is not covered by the turn-table. The end of the pitman entering the casing, is provided with a rack 43 in mesh with a pinion 44 within the casing 42; said casing having a slot indicated by dotted lines so constructed that the pitman 39 will have the proper adjustment and action. The shaft 44 of the pinion projects through the casing, and is provided with a milled head 45 and a pointer 46, the latter cooperating with a scale 47 on the casing.

Rigidly secured to that portion of the tone-arm 2 near the motor board and above the same is an arm 48 to the free end of which is pivoted at 48 a finger 49 projecting beyond the end of the arm in such a manner that in its path, when moved with the tone-arm, it will encounter the anti-friction roller 22 on'the end of the slide 19. A stop 50 limits the pivotal movement of the finger in one direction, and a spring 51 normally holds the tail 52 of the finger against the stop, but-will permit the tail to move away therefrom.

In connection with my invention, each record disk is provided with a tag, paster or label 53 affixed to the surface thereof in such a position that it will not interfere with the record groove thereon. On said label is noted the number indicating the last or inner groove of the record where the reproduction ceases. .The number indicating the inner groove is located in the manner hereinafter described.

The operation is as follows:

With the parts in the position shown in Fig.1, the brake shoe 15 is in engagement with the governor disk 10 on the governor shaft, and the motor is therefore at rest.v A record disk is placed upon the turn-table. The index finger 46 is rotated around until it points to the highest number on the dial 47, so that it can be readily and easily adjusted as hereinafter described. The tonearm 3 is swung over the record disk, and in its passage across the disk, the finger 49 will engage the anti-friction roller 22 on the end of the slide 19 and move the slide forward toward the auxilary spindle 13, until the pawl 32 is engaged by the shallow ratchet tooth 23. Such action will move the cam 17 under the button or head 14, thereby raising the auxiliary spindle 13, and releasing the brake shoe 15 from its engagement with the governor disk 10 on the governor shaft, and permitting the motor to operate, and to automatically start the turn-table. The rotation of the motor may be arrested by moving the lever 24 back against the stop 34 which will release the pawl 32 from the ratchet tooth 23, whereupon the spring 33 will move the slide 19 and cam 17 to the original positions, and the spring 16 will then force the brake 15 against the governor disk 10 and stop the motor.

The tone-arm will be moved over the face of the record disk until the stylus 5 is directly over the end of the record groove, and is held at that point. The index finger 46 is now rotated in the clock-wise direction until the depending lip 28 on the slide 26 engages the finger 49 on the arm 48 carried by the tone-arm. The position of the index 46 is noted, and the number indicated on the dial, to which the index points, is marked on the paster or label 53. As new records are provided, each may be marked in the same manner, and the end of its record groove noted on the paster as before. Such marking upon the record will indicate the end of the reproduction on the record, and will serve for any further playing of said record. Disks having extra long or unusually short record grooves thereon may be provided for by adjusting the device by means of the slot 38 in the pitman 39, Or the slot 18 in the extension of the cam 17, or both.

When a record proviously marked on the tag or label 53 is to be played, the index 46 ismoved until it indicates the number on the dial 47 corresponding to the number on the tag or label, in the present case 95. The disk is now placed on the turn-table, and the tone-arm is swung toward the center of the disk. Before the stylus 5 reaches a position over the outer end of the record groove, the finger 49 will engage the anti-friction roller 22 on the end of the slide 19', and move the latter forward toward the auxiliary spindle 13, until the'pawl 32 engages the ratchet tooth 23. The spring 33 will cause the pawl to engage the tooth, and will also swing the lever 24 away from the stop 34. The movement of the slide 19 will push the cam 17 under the button 14, thereby raising the auxiliary spindle 13, compressing the coil spring 16 and releasing brake shoe 15 from engagement with the governor disk 10, and thereby permitting the motor to operate and rotate the turn-table which will be running at normal speed when the stylus is engaged with the outer end of the record groove.

When the stylus reaches the inner end of the record groove, the finger 49 will contact with the downwardly extending projection 28 on the slide 26, and swing the lever 24 back against the stop 34. This movement will release the pawl 32 from the tooth 23, and the spring 33 will move the slide 19 back toits original position with the roller 22 in the path of the finger 49. The backward movement of the slide 19 will pull the cam 17 from beneath the button 14, lower the auxiliary spindle 13, and the tension of the spring 16 will apply the brake shoe 15 and arrest the movement'of the motor, and stop the turn-table.

When the tone-arm 3 is swung back to clear the turn-table to permit the removal of the record disk, the finger 49 will pivot against the spring 51 and pass the roller 22 without moving the slide 19, and the motor will remain at rest until it is engaged by the finger moving in the opposite direction.

All of the operative parts of the device, except the dial 47 and a small portion of the arm 48 are beneath the turn-table, and cannot be seen, and the apparatus will have the appearance of the ordinary machine minus the manually operated brake for the turn- 1 table.
